Why Must Optical Glass Have a High Degree of Transparency?

图片
As a   Dome Lens Manufacturer , share with you. The difference between optical glass and other glasses is that as an integral part of the optical system, it must meet the requirements of optical imaging. Therefore, the judgment of the quality of optical glass also includes some special and stricter indicators. Optical Glass Lense Today we will talk about the importance of optical glass that must have a high degree of transparency. The image brightness of the optical system is proportional to the transparency of the glass. The transparency of optical glass to light of a certain wavelength is expressed by the light absorption coefficient Kλ. After the light passes through a series of prisms and lenses, part of its energy is lost by the interface reflection of the optical parts and the other part is absorbed by the medium (glass) itself. The former increases with the increase of the refractive index of the glass. For high-refractive-index glass, this value is very large. For example, the

Is it necessary to install an optical lens for the high beam? Why is it necessary to install an optical lens for the high beam? What is the function? I believe that many people do not understand this problem. The function of optical lenses can be enlarged or reduced. The main purpose of installing optical lenses in automotive led headlights is to prevent the light source from scattering and improve the lighting of automotive headlights. Next,   Dome lens Manufacturer   wants to learn more about the pros and cons of the high beam lens. Optical Glass Lense Is it necessary to install an optical lens for the high beam? What are the benefits? The benefits of installing an optical lens for LED lights The LED car headlights need to be equipped with optical lenses to achieve the effect of condensing light. The light output brightness will not drop during use. The line-cutting star of the car light with a lens will not cause the headlight source to scatter and achieve a good condensing effect.

Construction of Active Infrared Detection System

Infrared non-destructive testing technology is based on the principle of infrared radiation. This technology uses measurement and analysis of infrared radiation to diagnose and inspect tested samples, such as equipment or materials. The infrared detection system combines the photoelectric system. The system presents the measurement signal through the thermal image obtained by the infrared detection device. Infrared thermal imaging detection technology is fast, non-contact, full-field and non-destructive, which is widely used in aerospace, machinery, industrial production and other fields. In order to achieve the ideal capabilities of detection and resolution, some detectors need to work at low temperatures. Therefore, some infrared detection systems use a refrigerator to cool the detectors. When the measured object is in a thermal equilibrium state, it is not easy to detect and analyze its internal conditions. At the moment, an external thermal excitation source is usually used to appl

What are the Main Points of Cleaning and Maintenance of Quartz Glass?

As a   Fused Silica Windows Manufacturer , share with you. Quartz glass is a single-component amorphous material of silicon dioxide. Its microstructure is a simple network composed of silicon dioxide tetrahedral structural units. Since the Si-O chemical bond energy is large and the structure is very tight, optical quartz Glass has the performance of DuTe, especially the optical performance of transparent quartz glass is very excellent, in the continuous wavelength range of ultraviolet to infrared radiation has excellent transmittance. Quartz glass has a very low thermal expansion coefficient, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, excellent transmission of ultraviolet spectrum and visible light and near-infrared spectrum Performance, and has higher mechanical properties than ordinary glass. Fused Silica Mirrors Quartz glass is an acidic material. Except for hydrofluoric acid and hot phosph
